Swapping and resynchronizing a TrueCopy or Universal Replicator pair using the DR Operator reverses the primary and secondary roles and restores data synchronization, ensuring both volumes are consistent after a failover or maintenance operation.

Verify that the VMs are powered-off before you perform the swap and resync operation.
Verify that the secondary site is up and running.

Note: This operation is not supported for Universal Replicator pair when multiple replication pairs are created using the same Journal ID.

Apply the DR policy with desiredState set to swap-resync. Enter:

kubectl patch drpolicy <drpolicy-cr-name> --type=merge -p '{"spec":{"desiredState":"swap-resync"}}

Verify if the DR policy is applied on both the primary and secondary sites. Enter:

 kubectl get drpolicy

Sample output:

kubectl get drpolicy
NAME                  SOURCE_CLUSTER   TARGET_CLUSTER   REPLICATION_TYPE   DESIRED_STATE   STATUS      CTG_ID   AGE
sample-app-drpolicy   site-61          site-62          sync               swap-resync     Unhealthy   21       25m

Verify the replication status of the PVCs. Enter:

kubectl get replication -A

Sample output:

NAMESPACE   NAME                                                 STATUS     DESIREDSTATE   OPERATION     AGE
         demo-app    replication--apps-1-drpolicy-sync--demo-server-pvc    Pair      swap-resync    swap-resync   25m
         demo-app    replication--apps-1-drpolicy-sync--demo-ui-pvc        Pair      swap-resync    swap-resync   25m
         demo-db     replication--apps-1-drpolicy-sync--demo-db-pvc        Pair      swap-resync    swap-resync   25m

You must also verify the replication status on the primary site.
